dunnhumby Network Alliance

dna (dunnhumby Network Alliance) is an open, collaborative Retail and Commerce Media service designed to unify a fragmented market and unlock growth for brands, agencies and retailers. Operating as a neutral layer across multiple retail partners, DNA brings together audiences, inventory and intelligence enabling a single, simplified point of entry to cross-retailer media at scale. Built in partnership with Kevel and powered by dunnhumby’s data and expertise, DNA connects brand and performance across the full customer journey, delivering more transparent, consistent and effective outcomes in an increasingly complex media landscape.

 

The Role

Act as the Product Director’s right hand on product, leading dna’s product strategy, portfolio, roadmap, and delivery. This is a senior level role combining technical, commercial, and customer judgement to create scalable products that deliver measurable P&L impact.

 

What You'll Be Doing

• Operate with high autonomy, owning dna's strategy, roadmap, and delivery end-to-end across campaign booking, inventory, targeting, measurement, and reporting.
• Make portfolio and investment trade-offs, converting complex choices into clear recommendations and decisions for executive leadership.
• Lead integrations and data flows across dunnhumby, Kevel, retailers, and publishers, turning partner needs into reusable, secure, and scalable platform capabilities.
• Use prototypes, experiments and AI/Gen AI to validate decisions, reduce delivery risk, and raise the bar while building it into dna's capabilities and ways of working.
• Own adoption, performance, and commercial outcomes, including positioning and monetisation through OKRs and revenue targets.
• Lead product practice, mentor PMs and represent the Product Director in senior internal and external forums, aligning stakeholders around decisions, investment, and outcomes.

 

What You’ll Bring

• Seasoned background in product, including experience in AdTech, MarTech or retail media at senior IC level.
• Proven 0-to-1 build and 1-to-N scaling across markets/partners.
• Deep AdTech fluency: DSPs, SSPs, ad servers, bidding, attribution, identity, closed-loop measurement.
• Experience with first-party data, clean rooms, and ML-driven targeting or measurement.
• Proven ability to set a multi-year product vision and raise the operating standard with the rituals, cadence, and quality bar across a wider product, data and tech team.
• C-suite credibility, commercial and investment judgement, and the ability to lead through ambiguity in a matrix organisation while applying AI pragmatically.
